Toshiba Introduces 500GB 2.5-inch Hard Disk Drive with Quiet Acoustics and Enhanced Durability
Toshiba Corporation today announced a new half-terabyte HDD, the flagship model in a series of 5,400 RPM SATA 3.0 Gbps 2.5-inch HDDs.
Available in capacities from 500GB to 120GB, the new series of quiet and durable drives is targeted for integration into notebook PCs, sub-notebooks, small form factor and energy star PCs, game consoles, external storage devices and consumer electronics products.
Advanced servo techniques combined with mechanical design changes minimize noise emanating from the drives, making them very quiet during operation. A further plus is that power consumption during data seek and read/write operation has been reduced by 0.5W, compared to Toshiba's current top-of-the-line 400GB HDD, to 1.7W and 1.4W, respectively.
In addition, optimization of mechanics and servo design boosts the durability of the series, to realize operating shock tolerances matching the highest levels available on the market today. To further protect user data against potentially hazardous external events, free-fall sensor (FFS) options are available in all models in the new series.
Toshiba's new drive series will begin shipping in production volumes to OEMs and distributors in December 2008 and will be exhibited at CES 2009 in January.

Other features:
- Halogen-free. The new drives achieve chlorine and bromine concentrations below 900ppm for each substance, and an overall total below 1,500ppm, achieving the standard required for recognition as Toshiba environmentally conscious products (ECP).
- Improved energy consumption efficiency. Compared to the 400GB model (MK4058GSX), the new 500GB HDD model (MK5055GSX) improves energy consumption efficiency, as defined under the Japanese legal standard, to 0.0012W/GB, a 20% improvement.
Lower CO2 emissions during the product lifecycle. During their lifecycle, the new drives will release approximately 95g a year less CO2 than their benchmark models.
- RoHS compatible. The new drives comply with the European Union's RoHS directive for eliminating use of six hazardous substances in electrical and electronic equipment.
